Choosing the best solar panel for a household can potentially improve the overall quality of your home and value for money. For many, adopting a residential solar energy system can be a wise decision. It can save a lot of money.

However there are a lot of factors to take into account for both residential spaces, such as the electrical, mechanical, financial, environmental, and customer-related factors are significant concerns for big corporations-On the other hand, payment plans, overall size, installation options, and reliability of the system are essential factors among households.

It would help significantly to consider a few essential factors before buying solar panels. Starting with the more nitty-gritty technical details, which are best known as they are at a basic level essential to understand prior to installing any solar panels.

A grid-connected solar power system has two essential elements: solar panels that generate electricity from sunlight and inverters that convert the electricity into a form ready for your home use. Some come with a monitoring system that allows you to know how much energy you’re generating and consuming.

Although solar batteries have yet to enter the mainstream market, the announcement of Tesla’s Home battery and other technologies pushes homeowners to add a battery to existing systems.

In addition, some important points to raise when understanding what to look out for and know include knowing that the overall efficiency of solar panels in the industry averages approximately 16/18%.

Ensure that you determine the solar panel’s warranty and compare it against the industry average of 10/25 years. Determine the overall costs and installation options, compare this cost with the efficiency of the overall technology available and provided.

Are Solar Panels Manufactured In Australia?

The Australian solar market is promising, and some of the manufacturers currently operating in the country are world-renowned. Below are some of the best’ value’ solar panel manufacturers in Australia.

Trina Solar, Jinko Solar, and Canadian Solar are among the oldest and most well-known producers. However, LONGi Solar has recently overtaken Trina Solar as the world’s largest monocrystalline cell manufacturer by sales.

How Much Does A Good Solar Panel Cost In Australia?

In Australia, solar panels cost approximately $5,250. After the government subsidy, this is the cost for the most common size (5kWh). Your household’s size and overall energy use will decide what solar panel system works best for you.

Solar panels cost $4,633 on average to deploy. The actual selling price range is $2,909 to $5,810, covering the range of different energy output systems from 1.5kWh to 6kWh solar panel systems. The reliability and overall built quality are subject to a specific manufacturer.

This would also be covered by certain incentives by local government schemes for energy saving that may assist in reducing such costs as well.

What Should You Check When Buying A Solar Panel?

Regardless of your initial goal for installing solar panels is for energy saving, financial reasons or for the environment and to assist in reducing hazardous pollutants in the air, making the shift to renewable energy such as solar power will offer many benefits both in the short term and long term.

Companies offer a variety of options to remain trendy in the market. There are two recent shifts that the industry has witnessed.

First, companies are introducing new emerging solar technologies. Second, the overall cost is declining because of competition in the market. Therefore, you’ll observe that many companies strive for attention.

Due to the advancements in renewable energy technology, costs to manufacture and produce better solar panels are also helping reduce costs. Well, what must you be checking when buying a solar panel in Australia?

As an expert in the energy efficiency space, including renewable energy, green energy, and solar technology, we got your back! To help you make a solid decision before you buy a solar panel for your household or any commercial space, here are some things you must check!

The size of solar panel

The first thing to consider is the size and compatibility of a solar panel.

Because Australia is in the southern hemisphere, experts also recommend putting all solar panels at a north-facing angle. Therefore, you must consider using a rooftop size that satisfies the angle recommendations and size requirements to save more for you.

A solar panel size no less than 5kW is a good starting point to install. However, the new sweet spot of a 6,6kW system with a 5kW inverter is a great alternative.

The cost of a 5kW panel differs depending on where you live, but you must plan between $5,000 and $8,000 for a quality, durable, and long-lasting solar panel, including the installation costs.

In addition, experts advise choosing a more significant system size than you may need. Because as long as you can afford the initial expense and have the required roof space. The following are the main reasons for this:

  • Higher feed-in tariffs
  • Larger systems have a lower cost.
  • Cost vs. value of more kWs: faster payback
  • Future storage and usage planning

The amount of electricity used during the day determines the size of the solar panel system (Expert Opinion)

Each day, the average Australian household uses 18 kWh of electricity. You may need a 5kW solar panel for a house in Adelaide to produce this amount of power. Nevertheless, installing such an extensive system is futile if the house only consumes 40% of its power during the daytime.

A setup that produces an average of 7.2kW (40 per cent x 18 kW) of energy per day will suffice in this scenario. As a result, a 3kW strategy can be the most cost-effective choice.

Efficiency of solar panel

The second most crucial factor that you may want to check is the efficiency of the solar panels. When purchasing solar panels in Australia and in general, the efficiency of the panels is a significant determinant.

Simply, it determines how well a solar panel can turn energy input or sunlight into energy output or electricity.

The higher the performance, the more effective the solar panel would be to charge their solar batteries quicker. Higher speed translates to more power even when the sun isn’t shining brightly.

Do you desire your panels to produce more energy? Of course, yes! So, how would you determine what solar panel to use depending on efficiency?

A typical panel efficiency should be around 15%–16%, where something between 17%–19% means slightly high, however, 20% efficiency is ideal.

Durability of a solar panel

The third factor that you must check when buying the best solar panel for your household or any other space, especially home, is “durability” and it can also be referred to as longevity or even a warranty for a product replacement.

Solar panel durability or lifespan is essential for various reasons, including indicating the maker’s trust in its product. Since solar panels with such an excellent reputation will go with a 25-year performance warranty.

Thus, this 25-year warranty duration covers all of our key modules that I have listed with crucial characteristics.

Therefore, it’s necessary to remember that warranties are only valid for as long as the business is in operation.

But, it’s yet another rationale to go for an excellently reputable brand (such as the ones mentioned previously of the solar panel unit rather than a minimal, obscure brand that might perish suddenly especially considering the high costs to replace and maintain them if there are constant issues.

Warranty periods (detailed overview) for an Australian buyer

It’s also vital to go with a solar panel that has a more extended warranty period.

And this consideration is essential, especially for a household buyer, so that they can choose a solar panel that offers a more extended service warranty as many panel companies make a 10-year warranty on average.

More recently, a 12-year warranty has become more common. There are a few companies that promise 20 years or more but they are uncommon. Regardless, however, it is important to also verify that your solar panels come with a performance warranty.

For example, if your solar panels have an estimated 20% efficiency and a max output power of 400W. In reality, it will have a minimum efficiency of around 16%. This means that the panel will produce a peak output power of 320 watts at its minimum efficiency.

Therefore, you can use it as a substitute if your energy use is less than this. Solar panels will also have a performance warranty of 20 to 25 to even 30 years.


Even if you’re reluctant to buy solar panels straight from the factory, still, you’ll choose a technician and retailer.

So, we must recommend going with one that provides your installation option to a service agent. Further, if you run into difficulty, the time it would take to resolve it will be far quicker.

To summarise, when purchasing solar panels, please ensure size, durability, efficiency, and warranty are altogether known in order to ensure you pick the best suited for your property.

Frequently Asked Questions

1. What are the economic advantages of solar energy?

Having solar panels on your house helps you save money on your electricity bills and prevents you from future power bills.

That amount you could save depends on your region’s energy costs and solar regulations, but choosing solar is a good investment no matter where you live.

2. Are solar panels eco-friendly?

Solar energy, like much renewable energy, do have environmental benefits. In addition, it keeps the environment a little safe from toxic chemicals such as sulphur and sulphur dioxide, which can be particularly hazardous.

3. Do my solar panels generate electricity even when the sun isn’t shining?

The percentage of sunlight available determines the quantity of power your solar energy system can produce. As a result, whenever the weather is cloudy, your solar panels will generate slightly less energy and no energy at night-time.

Solar is still a smart choice even if you live in a foggy city because of the increased energy costs and financial advantages.

 4. Which country produces the highest-quality solar panels?

China is the country’s biggest solar energy producer, with over 30.1 GW of PV capacity installed in 2019. On the list of top solar manufacturers, the United States, India, Japan, and Vietnam follow in second and third, correspondingly.

 5.Which solar panels should I choose for high temperatures?

For a hot climate or extreme temperatures, solar panels with a low temp characteristic are your best bet.

When the temperature rises a degree above the ideal temperature, which is 25 Celsius, the temperature coefficient is the amount by which the efficiency of solar panels decreases. As a result, the solar cells with the lowest cell temperature are the best for extreme temps.

6. Mono or Poly: Which is better for solar panels?

Monocrystalline panels beat polycrystalline panels since they use silicon ingots instead of silicon bits. So, the conclusion is mono; mono is better, even though poly is less costly.
